For instructions on calculating finance charges, refer to How to calculate Finance Charges (BB264800).

The Overall Past Due and Loan Balance method calculates a finance charge based on past due balances for charges and for a loan balance (for which payment is expected in the future). The finance charge is generated by adding the results of the Overall Past Due Balance and Loan Balance calculations.

**The Formula**

Finance changes are calculated using the following formula:

If calculating based on a period of days:

(**Total Overdue Balance**) x (annual finance charge % / 365) x Days

If calculating based on a period of months:

(**Total Overdue Balance**) x (annual finance charge % / 12) x Months

**How the Total Overdue Balance in the formula above is determined**

- Sum the unpaid charge balances as of the Calculate as of date of all charges associated with a fee subject to finance charge with a transaction date that is before or on the 'Calculate as of' date

**Note:**The unpaid charge balance is time sensitive. When looking at each individual charge, the system will disregard payments/credits with dates that fall after the 'Calculate as of' date that are applied to the charge.

- Sum the unpaid charge balances as of the Calculate as of date of all charges associated with a fee subject to finance charge with a transaction date that is greater then the 'Calculate as of; date

**Note:**The unpaid charge balance is time sensitive. When looking at each individual charge, the system will disregard payments/credits with dates that fall after the 'Calculate as of' date that are applied to the charge

- Sum the ungenerated advance deposits
^{(a)}(if selected), ungenerated financial aid^{(b)}(if selected), and unapplied payments and credits to calculate the Total Credit Available

- Total Overdue Balance = (Sum of unapplied charge balances in step 1) + (Sum of unapplied charge balances in step 2) - (Total Credit Available calculated in step 3)

Once the Total Overdue Balance is determined the appropriate values can be inserted into the formula above.

- How the system calculates ungenerated financial aid

Sum all of the ungenerated portions.

- Sum the unpaid charge balances as of the Calculate as of date of all charges associated with a fee subject to finance charge with a transaction date that is before or on the 'Calculate as of' date
